It is the first time the European Medicines Agency has cleared a COVID-19 vaccine for use in young children. Earlier this week, Germany’s health minister Jens Spahn said shipping of vaccines for younger children in the EU would begin on Dec. 20. The United States signed off on Pfizer’s kids-sized shots earlier this month, followed by other countries including Canada. Pfizer tested a dose that is a third of the amount given to adults for elementary school-age children. Still, WHO acknowledged that there are benefits to vaccinating children and adolescents that go beyond the immediate health benefits.
